Skating on thin ICE? Nope, you did get the facts correct.
With regards to the WR G3, they are technical an all season tire. However, because they use compounds that are designed to give the maximum grip based on the tires purpose, Nokian now calls everything all weather. This was explained to me by them a couple of months ago. Very few tires that are labeled all season have the mountain flake symbol indicating usage for winter conditions. The symbol also indicates that the tire is perfectly fine in jurisdictions that except it. Within some jurisdictions that except the symbol will still require on certain roads chains or studded tires depending on conditions. The Nokian Rotiva is an all season on/off road all terrain tire that additional has the mountain flake symbol giving that all weather status. Here is a link on other members opinions about the WR series: New tire
Goodyear tires for SUV's also uses the same label principles that Nokian does. The Silent Amror was labeled with the Mountain Flake for all weather as well.
Today, it is all about marketing and we as the consumer have to read between the lines.
Best for now.
